WCF - The socket connection was aborted

Question

I m getting the following Exception, when i run WCF service on a remote host with TCP binding. basichttpbinding works however.

Also, when i host it in the same machine, it works as well.

Also using test client and connection to remote machine, TCP works as well.

Why do you think i m getting the following exception? what s the fix?

Solution

When in doubt, turn on WCF diagnostics: http://msdn.microsoft.com/en-us/library/ms733025.aspx

I appreciate the points and all, but I would like to know what the root cause was as well. This was the best advice I was able to give with the available information at the time.
